AD7734
Reset
Rev. 0 | Page 23 of 32
The AD7734 can be reset by the RESET pin or by writing a reset
sequence to the AD7734 serial interface.
The reset sequence is N × 0 + 32 × 1, which could be the data
sequence 00h + FFh + FFh + FFh + FFh in a byte-oriented
interface. The AD7734 also features a power-on reset with a
trip point of 2 V and goes to the defined default state after
power-on.
It is the system designer’s responsibility to prevent an unwanted
write operation to the AD7734. The unwanted write operation
could happen when a spurious clock appears on the SCLK while
the CS pin is low. It should be noted that on system power-on, if
the AD7734 interface signals are floating or undefined, the part
can be inadvertently configured into an unknown state. This
could be easily overcome by initiating either a hardware reset
event or a 32 ones reset sequence as the first step in the system
configuration.
Access the AD7734 Registers
All communications to the part start with a write operation to
the communications register followed by either reading or
writing the addressed register.
In a simultaneous read-write interface (such as SPI), write 0 to
the AD7734 while reading data.
Figure 16 shows the AD7734 interface read sequence for the
ADC status register.

Single Conversion and Reading Data
When the mode register is being written, the ADC status byte is
cleared and the RDY pin goes high, regardless of its previous
state. When the single conversion command is written to the
mode register, the ADC starts the conversion on the channel
selected by the address of the mode register. After the
conversion is completed, the data register is updated, the mode
register is changed to idle mode, the relevant RDY bit is set, and
the RDY pin goes low. The RDY bit is reset and the RDY pin
returns high when the relevant channel data register is
being read.
Figure 17 shows the digital interface signals executing a single
conversion on Channel 0, waiting for the RDY pin to go low,
and reading the Channel 0 data register.
